Description
Technical Field
[0001] The utility model relates to the technical field of coconut milk processing, in particular to coconut milk squeezing equipment. Background Art
[0002] Coconut milk refers to a beverage product made from coconut pulp (juice) and (or) coconut pulp after squeezing coconut pulp as the main raw materials, with or without water, white sugar, edible salt, other plants, plant products, food additives, food nutrient enhancers and other raw and auxiliary materials, through blending, sterilization, filling and other processes. With the explosion of the concept of raw coconut, the number of brands producing coconut milk products in the market has increased sharply, and the market demand for coconut milk has increased, resulting in an increase in the supply price of raw materials such as coconuts. The original rough equipment and methods for squeezing coconut milk have increased due to their low squeezing efficiency, resulting in increased processing costs.
[0003] Most of the current coconut milk extraction equipment uses roller rolling for cold pressing. The coconut meat passes through the gap between two rollers or the roller and the pressing plate, so that water and oil are squeezed out to form coconut milk. The coconut meat residue after being squeezed once still retains some water and oil. There are generally two options for these coconut meat residues. One is to collect them and put them back into the extraction equipment for secondary extraction. However, due to the extraction efficiency problem of the extraction equipment, the secondary extraction pulping rate is low, so another method will be chosen during the processing, that is, the coconut meat residue is directly used to make other products or discarded.
[0004] Therefore, it is necessary to redesign a coconut milk extraction device, which can improve the one-time pulping rate on the one hand, and can also automatically and repeatedly squeeze the coconut meat residue on the other hand to improve the final pulping rate of the extraction device, thereby achieving the purpose of cost saving. Utility Model Content
[0005] The utility model aims to provide a coconut milk squeezing device to solve the problems described in the background technology.
[0006] The technical solution of the utility model is achieved in this way:
[0007] A coconut milk squeezing device comprises an squeezing box arranged on a supporting seat, a feed hopper is arranged at the top front end of the squeezing box, a slag outlet is opened on the side wall of the squeezing box, a pulp outlet pipe is arranged at the bottom of the squeezing box, an upper squeezing plate and a lower squeezing plate are fixedly arranged in the squeezing box, the upper end face of the upper squeezing plate is a stepped inclined surface with a rear end lower than the front end, the upper end face of the lower squeezing plate is a stepped inclined surface with a rear end lower than the rear end, the step is a circular arc wall concave downward, a corresponding squeezing roller is arranged above the circular arc wall, both ends of the squeezing roller are provided with a rotating shaft and are rotatably installed on the left and right box walls of the squeezing box through the rotating shaft, a plurality of roller convex points are arranged on the roller surface of the squeezing roller, the circular arc wall of the lower squeezing plate is also provided with wall convex points staggered with the roller convex points of the squeezing roller, the central axis of the circular arc wall is parallel to the axis of the squeezing roller The central axes coincide with each other, and when the squeezing roller rotates, the roller convex points and the arc wall fit together and rotate, and the wall convex points and the roller surface of the squeezing roller fit together and rotate. An inclined filter plate is also provided below the lower squeezing plate, and the lowest point of the filter plate is connected to the slag outlet. The side wall of the squeezing box is also provided with a vertical lifting auger, and a slag inlet is provided at the lower end of the side wall of the lifting auger, and a slag discharge port is provided at the upper end of the side wall of the lifting auger. The slag outlet is connected with the slag inlet, and an inclined pipe is connected to the slag discharge port, which is penetrated in the box wall of the squeezing box, and the end of the inclined pipe extends to above the front end of the upper squeezing plate. A driving mechanism is also provided outside the squeezing box, and the rotating shaft passes through the side wall of the squeezing box and is connected to the driving mechanism. A slag cleaning port is also provided on the side wall of the squeezing box opposite to the front end of the lower squeezing plate, and a box door is provided at the slag cleaning port.
[0008] When the above scheme is used, coconut meat is put into the squeezing box from the feed hopper. After being put into the squeezing box, the coconut meat falls to the front end of the upper squeezing plate and slides down along the upper end surface of the upper squeezing plate. When passing through the squeezing roller, the coconut meat falls to the arc wall. The squeezing roller squeezes and squeezes the coconut meat through the roller surface and the roller convex point. Since the central axis of the arc wall coincides with the central axis of the squeezing roller, the roller convex point and the arc wall rotate in contact with each other when the squeezing roller rotates, so a section of the roller surface of the squeezing roller and the arc wall form an squeezing surface, the squeezed surface of the coconut meat increases, and the roller convex point further squeezes the coconut meat, thereby improving the coconut milk squeezing rate.
[0009] After the first squeezing, the coconut meat falls from the rear end of the upper squeezing plate to the rear end of the lower squeezing plate, and slides toward the front end along the upper end surface of the lower squeezing plate. When passing through the squeezing roller, it falls to the arc wall. Because the wall convex points at the arc wall of the lower squeezing plate and the roller convex points of the squeezing roller are staggered with each other, a narrower squeezing gap is formed. When the coconut meat passes through the squeezing gap formed by the wall convex points and the roller convex points, coconut milk is further squeezed out.
[0010] After the second squeezing, the coconut meat falls onto the filter plate, the coconut milk drips through the filter plate to the bottom of the squeezing box and is discharged from the slurry discharge pipe, while the coconut meat enters the lifting auger through the slag discharge port and the slag inlet, and is transported to the slag discharge port at the upper end by the lifting auger, and returns to the front end of the upper squeezing plate from the inclined tube for repeated squeezing.
[0011] After multiple rounds of repeated squeezing until no coconut milk flows out of the pulp outlet pipe, open the box door, insert the external flat plate from the residue cleaning port to the bottom of the front end of the lower extrusion plate, and fix it. As the equipment circulates, the coconut meat residue is also transported to the flat plate and discharged from the residue cleaning port along the flat plate.
[0012] A further technical solution is that the extrusion roller corresponding to the arc wall at the step of the upper extrusion plate is the upper extrusion roller, and the roller convex points of the upper extrusion roller are distributed along a straight line in the extension direction of the central axis of the upper extrusion roller, thereby forming a plurality of roller convex point connecting lines, and the roller convex points in the same roller convex point connecting line are distributed at equal distances, and the plurality of roller convex point connecting lines are distributed at equal angles with the central axis of the upper extrusion roller to which they belong as the center, and the roller convex points on adjacent roller convex point connecting lines are staggered in the left and right directions.
[0013] When the above scheme is used, by setting roller convex point connecting lines arranged at equal angles, setting roller convex points at equal intervals, and staggering the roller convex points on adjacent roller convex point connecting lines in the left and right directions, the coconut meat can be better squeezed when passing through the arc wall of the upper squeezing plate, thereby improving the coconut milk extraction rate.
[0014] A further technical solution is that the extrusion roller corresponding to the arc wall at the step of the lower extrusion plate is the lower extrusion roller, and the roller convex points of the lower extrusion roller are distributed along a straight line in the extension direction of the central axis of the lower extrusion roller, thereby forming a plurality of roller convex point connection lines, and the roller convex points in the same roller convex point connection line are distributed at equal distances, and the plurality of roller convex point connection lines are distributed at equal angles with the central axis of the lower extrusion roller to which they belong as the center, and the roller convex points on adjacent roller convex point connection lines are aligned in the left-right direction, and the wall convex points on the arc wall of the lower extrusion plate are distributed along a straight line in the extension direction of the central axis of the arc wall to which they belong, thereby forming a plurality of wall convex point connection lines, and the wall convex points in the same wall convex point connection line are distributed at equal distances, and the plurality of wall convex point connection lines are distributed at equal angles with the central axis of the arc wall to which they belong as the center, and the wall convex points on adjacent wall convex point connection lines are aligned in the left-right direction.
[0015] When using the above scheme, by setting roller convex point lines and wall convex point lines arranged at equal angles, setting roller convex points and wall convex points at equal intervals, and aligning the roller convex points on adjacent roller convex point lines with each other in the left-right direction, and aligning the wall convex points on adjacent wall convex point lines with each other in the left-right direction, the extrusion gap formed by the roller convex points and the wall convex points is made more uniform, thereby further improving the coconut milk extraction rate.
[0016] A further technical solution is that the front, left and right ends of the upper extrusion plate are fixedly connected to the front, left and right walls of the extraction box, and the rear, left and right ends of the lower extrusion plate are fixedly connected to the rear, left and right walls of the extraction box.
[0017] When the above solution is used, the connection between the upper extruded plate and the lower extruded plate is more stable.
[0018] A further technical solution is that there are at least three steps on the upper end surfaces of the upper extrusion plate and the lower extrusion plate respectively.
[0019] When using the above scheme, the coconut milk extraction rate is further improved by setting multiple steps.
[0020] A further technical solution is that the driving mechanism includes two driving motors fixedly mounted on the outer side wall of the extraction box, a driving wheel is fixedly mounted on the output shaft of the driving motor, and the parts of the rotating shafts of the upper squeezing roller and the lower squeezing roller that pass through the side wall of the squeezing box are also respectively provided with two driven wheels, a driven wheel on the rotating shaft of the upper squeezing roller on the edge of the multiple upper squeezing rollers is driven and connected to a driving wheel on a driving motor, and adjacent upper squeezing rollers are driven and connected to each other in the same direction of rotation via the driven wheels on their respective rotating shafts, a driven wheel on the rotating shaft of the lower squeezing roller on the edge of the multiple lower squeezing rollers is driven and connected to a driving wheel on another driving motor, and adjacent lower squeezing rollers are driven and connected to each other in the same direction of rotation via the driven wheels on their respective rotating shafts.

[0023] When the above solution is used, the flat filter plate is provided, so that the coconut pulp can slide more smoothly and more efficiently.
[0024] A further technical solution is that a pulp outlet hopper is also provided at the inner bottom of the squeezing box, and the pulp outlet pipe is arranged at the lowest point of the pulp outlet hopper.
